  • Patent number: 4049759
    Abstract: A method and arrangement for lining articles are disclosed which are particularly well-suited for use in lining melting ovens. The arrangement includes a mold member which is composed of several relatively movable sections so as to permit the dimensions thereof to be changed. For the lining of an oven chamber, the mold member has an external surface the configuration of which corresponds to the inner wall of the oven chamber. This surface is coated with a refractory-containing composition, which is releasably secured over the surface. In coating the mold member the composition is made up in a flowable or plastic state, applied over the external surface of the mold member in this state, and then hardened, for instance, by heating. The composition is of such a nature that the temperatures required for hardening the same are sufficiently low to avoid undesirable effects on the mold member.
